Cost & budgeting
How should a facility manager budget a window film project?
Budget by elevation rather than by building, and get a survey before the number goes into a capital request. Treating only the elevations that generate complaints typically removes a third or more of the assumed area, and it prevents spending daylight and money on glass that never needed treatment.
The most common budgeting error is pricing the whole building. North glazing usually needs nothing. Shaded elevations frequently need nothing. A survey that maps complaints against orientation and glass construction turns a rough building-wide number into a scope you can defend line by line.
The second error is treating security film as a film line item. Where forced-entry delay is the objective, perimeter attachment is a separate material and labour scope with its own linear-foot quantity — it belongs on its own line so it does not get value-engineered out silently.
If the work will be phased across fiscal years, lock the product specification at phase one and record it. Film products change across generations, and a single elevation carrying three purchasing cycles of similar-but-different film is visible from the street.
A defensible budget package
- Survey-based scope by elevation with areas and opening counts
- Product specification recorded per building
- Attachment quantities as a separate line where security is in scope
- Access method and after-hours assumptions stated
- Phasing plan with the specification locked at phase one
